Answer 1

1. True2. False3. True4. True

Answer 2

An element is a fundamental substance that cannot be chemically broken down into a simpler form. This aligns with the definition of an element in chemistry. Therefore, the first statement is correct. The second statement is incorrect because it describes a compound or a molecule, not an element. An element is made of only one type of atom, not two or more atoms chemically combined. The third statement is correct as all known elements are indeed listed on the periodic table of elements. The fourth statement is also correct; it describes the standard notation for elements where the first letter of the symbol is capitalized and any subsequent letters are lowercase.
